CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

This vulnerability is a SQL injection issue found in the Class and Exam Timetabling System version 1.0, specifically in the file /archive1.php. It occurs due to improper input validation of the 'sy' parameter, which allows an attacker to inject malicious SQL code remotely without needing authentication.

Attackers can exploit this vulnerability using techniques such as boolean-based blind or error-based SQL injection to manipulate the database.

Impact Analysis

Exploitation of this vulnerability can lead to unauthorized access to the database, allowing attackers to view, modify, or delete sensitive data.

It may also result in a full system compromise depending on the database permissions and the extent of the injection.

Detection Guidance

This SQL injection vulnerability in the /archive1.php file can be detected by testing the 'sy' parameter for SQL injection flaws using boolean-based blind or error-based SQL injection techniques.

  • Use tools like sqlmap to test the 'sy' parameter for injection, e.g., sqlmap -u "http://target/archive1.php?sy=1" --batch
  • Manually test by injecting SQL payloads such as ' OR '1'='1 or ' OR 1=1-- into the 'sy' parameter and observe if the response changes or errors occur.
  • Monitor network traffic for suspicious requests targeting /archive1.php with unusual or malformed 'sy' parameter values.
Mitigation Strategies

Immediate mitigation steps include implementing prepared statements and proper input validation on the 'sy' parameter to prevent SQL injection.

  • Sanitize and validate all inputs to the /archive1.php script, especially the 'sy' parameter.
  • Use parameterized queries or prepared statements in the database access code.
  • Minimize database user permissions to limit the impact of a potential injection.
  • Conduct regular security audits and code reviews to detect and fix similar vulnerabilities.
Compliance Impact

The SQL injection vulnerability in the Class and Exam Timetabling System allows unauthorized database access and data manipulation, which can lead to exposure or alteration of sensitive information.

Such unauthorized access and potential data breaches can negatively impact compliance with data protection regulations like GDPR and HIPAA, which require safeguarding personal and sensitive data against unauthorized access and ensuring data integrity.

Failure to address this vulnerability could result in violations of these standards, leading to legal and financial consequences.
